My invention relates to armored concrete floors more especially of thekind comprising filling blocks. It is an object of'my invention to provide a concrete floor of this kind in which the filling blocks are arranged to take up and transmit compressive strain.

' In the majority of hollow blockfloors, the

hollow blocks merely serve as fillers which at the same timeafford a betterinsulation than solid concrete slabs, the weightoflthe floor being [also inferior to the Weight of a fioor'comprising such solid slabs, In order to effect a saving in the depth of the work and to obtain a suitable: bond between the concrete bea1ns,-thehollow blocks'in these floors are as a rulecovered with'a concrete layer a few centlm'etres high. In: consequence of this concrete layer superposed on the filling blocks, the floorcoverings' direct- 1y resting on the floors remain cold and floors of this" kind are comparatively weighty; If the superposed. layer, of concrete is dispensed with, a considerably greater depth of thework becomes necessary. Moreover, in this case there exists no bond between the single beams and in consequence thereofsuch ,fioors are very sensitive against the support of heavy single loads and in many caseswill become prac tically useless. 1 r According to the prese t invention the tops of the filling blocks which are arranged in rows, differ in height and the interstices between the blocks are filled with transverse 5 concrete beams which are armored by means of distribution bars extending across the rows-of filling blocks, which are'united by armored concrete beams 1 extending in the longitudinal direction of and between these rows of blocks, as usual. In the drawingsafiixedto this specification and forming part thereof two forms of a concrete floor embodying-my invention are illustrated diagrammatically by way of ex- 5 ample.

In the drawings I Fig. l is a perspective view of some rows of filling blocks and reinforcement and repartition bars mounted in-place, before be-- ing'covered with concrete.

.Fig. 3 is a longitudinal section on the line III-III in Fig. 1. j V I Fig. 4 is a perspectiveview of a second modification. I

Referring first to Figs. 1-3, each row of filling blocks consists of large high blocks m I andsmaller and lower blocks n inserted between-the blocks m. The several rows of blocks are spaced apart for the insertion of longitudinal reinforcement bars 0 extending in parallel to the rows of blocks, while, 29 are'repartition bars extending across the rows of blocks between the large blocks m blocks 1, low slabs 8 being placed in spaced relation on top of these blocks, preferably so asto cover the joints, and the repartition bars extend across the rows of large blocks 77,

resting 'on their top surfaces between the end faces of adjoining smaller slabs s. I
